From the project
minimoog filter from gerbster.nl. rebuilt ioboard and panel
Thomas henry 555 vco with panel. based on Eagleproject from Gerbster.nl.
imported to kicad. IO board redesigned for a more logical layout and extra audio and CV input.
PCBS ordered from JLCPCB. will update after building and testing.

Mainboard: common questions
How big is the Mainboard PCB?
The Mainboard measures 99.7 × 41.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mainboard?
59 components, from 33 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mainboard design files?
From the B0rgar/minimoog_VCF repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mainboard design in my own project?
The repository has no license, so all rights stay with B0rgar. Use it as a reference, and ask the author before reusing the design.
